United States 2 Claims. (Cl. 68-177) This invention relates toimprovements in bin piling apparatus of the type shown and described inU. S. Letters Patent 1,478,846 of December 25, 1923, to P. W. Bidwell.

The principal objects of the invention aredirected to cloth rope guidingor laying mechanism for bin piling apparatus of the type referred to insaid patent wherein an elongated protective sleeve is provided for anelongated right and left hand screw which moves a pot-eye for a clothrope back and forth in piling the cloth in a bin or vat.

A bin piler is used in textile plants and over a vat or bin and the likewherein cloth is laid for processing. The screw of the bin piler isdisposed for horizontal rotation in one direction and a pot-eye is movedback and forth by the screw. A follower of the pot-eye is in engagementwith the right and left hand screw threads or grooves of the screw sothat it traverses the screw back and forth, for laying the rope of clothin a bin or vat.

A web of cloth for laying in the vat or bin is bunched up somewhat inthe form of a rope and is passed through the pot-eye for laying of thecloth in the vat or bin.

No end of difficulty has been experienced with bin pilers due to lintand the like settling on the traverse screw and drippings therefrom ontocloth therebelow.

Lint and other substances on the screw not only interfere with thesmooth operation of the apparatus but also bring about abrasion of theparts so that wear is excessive.

The screw and follower must be lubricated and such not only contributesto the collection of lint and abrasive substances, but also drippings oflubricant from the screw onto the cloth in the bin is injurious andobjectionable.

According to one novel feature of the invention, a screw shell isprovided around the screw which prevents lint and foreign substancesfrom settling thereon thereby to insure smooth operation and less wearcaused by abrasion, and the shell provides a means for adequatelubrication of the screw without the danger of drippings of lubricantonto cloth in the bin therebelow.

According to another novel feature of the invention, the pot-eyecomponent is reciprocable along the screw shell by which it issupported. In this manner, the pot-eye component is supportedindependently of the screw so that the screw is not burdened by theweight of the pot-eye and the cloth of rope therein so that wear of thescrew by the pot-eye component is eliminated.

The foregoing is accomplished by mounting the pot-eye component on thescrew shell for its back and forth reciprocation.

Various novel features of the invention will be ob served from thefollowing description of the present preferred form thereof and it willbe observed that changes and modifications may be made in the apparatuswithout departing from the spirit and scope of the invention set forthin the appended claims.

In the drawings:

Fig. 1 is a side elevational view of cloth guiding or laying mechanismof the invention;

atent Fig. 2 is a plan view of the carriage of the mechanism, shown in'Fig. 1;

Fig. 3 is a plan view of an end portion of the shell of the mechanism,shown in Fig. 1;

Fig. 4 is a sectional elevational view through the end portion of theshell and of the carriage; and

Fig. 5 is a sectional elevational view on the line 5-5 of Fig. 4.

Referring'now to the drawings in detail, the novel features oftheinvention will be fully described:

'So much of a bin piler, as opposite side portions 2 and 4, are shown asis necessary in order to describe the invention in the present preferredform thereof. The portions 2 and 4 correspond to the side members 20 ofthe carriage 5 of Patent #1,478,846, previously referred to.

An elongated shell 6 for a traverse screw extends between said endportions and a traverse screw 8 extends within and longitudinally of theshell. Opposite ends of said screw are journalled for rotation inbearings 10 shown as 'secured'tothe end portions 2 and 4. The screw 8maybe rotated at either end by suitable driving mechanism associatedwith either side portion of the piler carriage.

The shell and screw will be mounted horizontally so that a longitudinalslot 12 of the shell will be disposed along the upper side thereof.Opposite ends of the shell may be secured to the bearings 10 by anysuitable means.

The screw 8 is provided with helically and longitudinally extendingright and left hand follower grooves 14 and 16 which intersect or crossone another.

A carriage 18 is provided with a bushing or bearing 20 on and around thesleeve 6 for easy reciprocation of the carriage back and forth alongsaid sleeve. Said bushing will be of such material as to require noappreciable amount of lubricant, if any at all, along the sleeve.Various commercial bushing materials are available for the purpose.

A follower 22 is provided which has a lower inner arched or more or lessserni-cireular portion 24 which is engageable in the threads or groovesof thescrew.

An upper outer end 26 of the follower in the form of a stem or pin 26 isoscillatable in a follower holder or block 28. Said block extendsthrough and is slidable up and down in a suitable opening provided inthe upper side of the carriage.

The block 28 is secured to the lower side of a plate 30 by rivets,screws or the like indicated by 32. Plate 30 is connected to the upperside of the carriage by screws 34.

The block 30 may be readily removed by removing the screws 24 for accessto the follower. A spring 36 between the stern of the follower and plate30 urges the follower into the grooves of the screw.

The upper side of the shell 6 is provided with a transverse slot 12which intersects the slot 12, as shown in Fig. 3. By aligning thefollower 22 with the slot 12' and removing plate 30 from the carriage,the follower may be removed.

The carriage 18 has a depending portion 40 which is slidable along aguide rod 40'. Said guide rod 40 has its opposite ends fixed in brackets2 and 4 which are secured to the side members 2 and 4. The guide rod 40'prevents turning of the carriage 18 about the shell 6.

P represents a pot-eye, of usual form, which is carried by the carriage18 and through which a rope of cloth passes that is to be laid in a binas the carriage moves back and forth on the shell.

In operation, the screw is rotated in one direction. The grooves of thescrew at the ends thereof are so arranged that as the follower reachesthe end of the groove of one hand said follower is turned on its sternso as to enter the entrance end of the groove of the other hand. Thus,as the screw rotates, the carriage is moved back and forth on the shell.The connected ends of opposite grooves are shown at 15 in Fig. 4.

It will be noted that the carriage is reciprocable on the shell so as torelieve the screw of weight. The screw is protected against foreignsubstances settling thereon while at the same time said screw may beadequately lubricated without danger of drippings therefrom.

It will be noted that the screw and shell are out of contact 'so as toprovide a longitudinal space therebetween and that the carriage is notonly reciprocable along the sleeve but also supported entirely therebyto relieve the screw of its weight. The spacing of the screw and shellnot only provides for adequate lubrication of the screw and follower butalso there may be deflection of the shell due to the Weight of thecarriage and cloth supported thereby Without affecting the screw.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

1. Apparatus for guiding a cloth rope and adapted for association withthe horizontally spaced side members of the carriage of a bin pilercomprising in combination, an elongated tubular shell having oppositeends fixed to bearings adapted to be secured to horizontally spaced 25side members of a bin piler carriage, a traverse screw having right andleft hand intersecting helical grooves extending along and within saidshell journalled at opposite ends in said bearings for rotation relativeto said shell, a carriage surrounding and slidably supported by saidshell for movements back and forth along said shell, said shell providedwith a longitudinally extending slot on the upper side thereof, saidcarriage provided with an opening in the upper side thereof, a plate andmeans removably securing said plate to the upper side of said carriage,a holder secured to and depending from said plate into and through theopening of said carriage and longitudinal slot of said shell, saidholder provided with a vertical bore, a follower having an upper portionoscillatable in the bore of said holder and a lower portion operativelyengaging the grooves of said screw, and said shell provided with a slotin the upper side thereof crossing the longitudinal slot thereof forremoval of the follower therethrough on removal of said plate and holderfrom the carriage.

2. Apparatus for guiding a cloth rope set forth in claim 1 wherein theouter side of said screw is slightly out of contact with the inner sideof said shell, to provide an annular space between said screw and shell.
